Abstract
A schematic Monte Carlo simulation is used to examine the potential of the \({\overline{\rm P}} {\rm ANDA}\) experiment to extract information on the interaction of antihyperons in nuclei by exclusive hyperon-antihyperon pair production close to threshold in antiproton nucleus interactions. Due to energy and momentum conservation event-by-event transverse momentum correlations of the produced hyperon and antihyperons contain information on the difference between their potentials. It is demonstrated that for \({{\Lambda}{\overline{\Lambda}}}\) and \({{{\Xi}}{{\overline{\Xi}}}}\) pairs produced at antiproton momenta of 1.66 GeV/c and 2.9 GeV/c, respectively, the asymmetry is sufficiently sensitive even if the density as well as the momentum dependencies of the potentials are considered.
